GPS monitors deformation in subduction zone: Part A intro

How can we model how GPS works?

Instructional video shows how to conduct 5-step student activity to build gum-drop GPS station, learn how GPS works, then model and graph the GPS movement.

This video, Part A, covers Steps 1 and 2: building and using a gumdrop GPS station.

In Part B (steps 3-5), students learn how to read time-series plots and understand how we know the ground is moving.
